the Sheeps running in the Meadows at thelater end of la. 
Autumn, and eating Grafs that was either actually frozen, 
or cover'd with coid Dews, was the true reafon their Lungs 
were thus fpoil d 5 and that the famQ happened fometimes 
But for my part, I ftiould rather conclude that the fro- 
zen Grafs does not hurt their Lungs, but Stomachs, and 
that the cold Air does not afFcft their Liings. 
Knowing that our Butchers fetch abundance of Fat Sheep 
from Brabam^ and that thofe Sheep are driven every morn- 
ing into the Fields and folded every night by their Shep- 
herds 5 and that our Sheep, on the contrary, are brought 
into the Meadows in May^ and there left till it Snows and 
Freezes^ I askt the Butcher whether the Brabant Sheep had 
fuch bad Lungs as ours 5 and was anfwer'd. Seldom or 
never. 
From whence I was ftill better fatisfied, that the Dif- 
cafes in the Lungs of Sheep, and efpecially of fuch as lye 
in the Field in the long cold Nighrs, were occalion'd by 
notjiing elfe but their lucking in the Cold Air. 
I askt moreover whether fuch Sheep were Fat whilft 
they were kept up, and whether they could diftinguifli 
while living which had bad Lungs 3 to wliich they an- 
fwer\l, that thofe v/hofe Lungs were toucht, did never 
increafe in fat after they were ftall'd 3 and that within a 
fortnights time after they had been fliut up,, and fed with 
Beans in order to fatning, the Diftemper ufually difclofed 
it felf, for they did nothing but Cough, and therefore 
they always kili'd thofe Sheep firft. 
Now if we allow that the Cold Air is fo prejudicial to 
the Lungs, we ought not to wonder if fuch an Inconveni- 
ence ( as we call a Cold ) comes upon them, tho we are 
able to difcQver from whence it proceeds. 
Yea, I am of opinion, that in a long cold Winter the 
Lungs may be fo much incommoded, that a great fit of 
Sick-
